A widow's peak hairline (W) is dominant to straight hairline (w). Cross a heterozygous widow's peak hairline person with a straight hairline person. What are the genotypic and phenotypic
ratios of their offspring

Use a punnett square! I'll attach an example.

Genotype - Genetic constitution of dominant and recessive traits inherited from parents. BB, Bb, & bb can be used to represent these.

Phenotype - Observable. If a dominant trait is present, it shows as the phenotype. For example, brown hair is dominant to blonde hair. A person with a BB or Bb genotype will have brown hair, but a person with a bb genotype will have blonde hair.

Statistically, they have a 50% chance of a child with a widow's peak, and a 50% chance of a child with a straight hairline.
